While Kristen Stewart was letting her hunk boyfriend Robert Pattinson spend some boys night out, such freedom does not always does her good. After Rob recently struck some friendship meeting at a club to discuss a film project with Vince Vaughn, his new BFF has apparently advised the 26-year-old actor to dump Kristen. Read on and find out why.

Showbizspy is reporting that Vince had told Robert straight up that he may have to think about letting Kristen go.

“When Rob described how he took Kristen back after she cheated, Vince said, ‘That’s a mistake – a big one,’” a source was quoted as revealing Showbizspy.

The ‘momentary indiscretion’ Kristen had with her former director in Snow White and the Huntsman has been the core issue raised on Vince’s reported advice to dump Kristen.

“He told Rob he knows how easy it is to fall into a routine, but when your girl cheats on you, you should take that as a sign that you should probably end things,” the source added.

Vince has a common ground with Rob and the British hunk’s relationship with Kristen. Like Rob who met K-Stew on set of Twilight series, Vince met A-list actress, Jennifer Aniston on the set of The Break-up. Though cheating was never an issue between Vince and Jennifer that caused the split, Vince reportedly pointed out that while it was a great relationship with Jen, he knew when it was not the time to get serious.

The insider added, “Vince said he and Jennifer [Aniston] had a great time together [with their on-set romance] but he can’t imagine settling down with someone at 26, like Rob is doing – especially someone who cheated on him … Vince told Rob he was 40 before he was done sowing his wild oats.”

Vince’s advice fell on deaf ears since Rob loves Kristen more than anything else - - if you will measure his love with the affection and attention he has been showering Kristen with since his return from filming The Rover in Australia. But Vince’s advice has made an impact on the Twilight hunk.

“Vince got him thinking, for sure … but there’s a level of comfort he has with Kristen that he’s scared of losing.”

Following Rob’s night out with Vince (and Joaquin Phoenix) at a private party in The Larchmont more than a week ago, the Robsten Romance has been kept alive. The couple was spotted cozy and loved-up at the Coachella Festival 2013, and they were spotted taking errands together and partying with friends, with no sign of any relationshop troubles.
